this term refers to the dissolution of cell nuclei in dying cells. In Hematoxylin and Eosin stains a very early sign of karyolysis may be a lessening of nuclear basophilia, i.e., less staining with hematoxylin. Karyolysis is usually followed by pyknosis, a shrinking of the nucleus that is associated with an increase of nuclear basophilia.
